Industry Analysis
Micron’s 704% stock surge reflects real demand, not speculation: AI infrastructure urgently needs HBM. Technologically, HBM3E/HBM4 is straining TSV and CoWoS packaging capacity, making Taiwan, China-based OSATs like TSMC critical bottlenecks. On compliance, U.S. export controls on advanced tools inflate Micron’s Southeast Asia fab costs, while its Xi’an facility in mainland China faces geopolitical scrutiny. Competitively, Samsung is fast-tracking HBM4 to reclaim share, and SK Hynix is locking in NVIDIA allocations—setting up a fierce 2026 capacity war. Over the next 12–24 months, persistent HBM shortages will empower pricing leverage, but if AI cluster deployment slows, a correction could hit by Q2 2027. Current valuations already price in peak optimism.
